CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 447,640, dated March 3,1891.

Application filed October 10, 1890. Serial No. 367,669. (No model.)

To all whom it may concern.-

Be it known that I, MICHAEL F. FINNERTY, of Brooklyn, in the county ofKings and State of New York, have invented a new and Improved Coupling,of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved coupling,which is simple and durable in construction, very effective, andautomatic in operation, and specially designed for coupling carstogether or ferryboats to their slips, the.

The invention consists of a transverse bar adapted to slide verticallyin the draw-head and provided with a pin projecting at right angles tothe said bar, and a coupling-link adapted to be engaged by the said barand pin.

The invention also consists in certain parts and details andcombinations of the same, as will be described hereinafter, and thenpointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of the improvement with parts broken out. Fig. 2is a sectional side elevation of the same on the line a :0 of Fig. 1.Fig. 3 is a front view of the same with parts broken out and parts insection. Fig. 4 is a side elevation of a modified form of coupling-link,and Fig. 5 is a plan view of another improved form of coupling-link.

The improved coupling is provided with a draw-head A, havingin its frontend two compartments B and 0, one located above the other and bothadapted to receive the coupling-link D. In the upper part of thedrawhead A is fitted to slide vertically atransverse bar E, extendinginto the upper compartment 0, and from the said bar extends downward, ator near its middle, a pin G, passing through the partition between thetwo compartments and into and through the lower compartment 13. The endsof the transverse bar E are provided with'downwardly-extendi11g arms E,fitted to slide vertically in suitable guideways F arranged on the sidesof the draw-head A.

The coupling-link D previously mentioned is provided with a link properD, adapted to pass into the lower compartment B to be engaged at one endby the pin G. From the middle of this link proper D extends upwardly apartition D which supports a horizontally-extending bar D arrangedparallel with the link proper D, and adapted to'pass into the uppercompartment 0. The ends of the bar D are forked,as is plainlyillustrated in Fig. 1, the prongs of each fork being provided withupwardly extending hooks D, adapted to travel under the rounded-offbottom of the transverse bar E, so as to raise the latter and pass tothe rear thereof, in order to be engaged thereby when the said bar E hasdropped. \Vhen the link D passes at one end into the draw-head A, therespective hooks E cause an upward sliding of the transverse bar E, sothat the lower end of the pin G is raised to the top of the compartmentBto permit the link proper D to fully enter the compartment B. When thehooks D have passed to the rear of the bar E, the latter drops, then thepin G slides downward with the bar E and engages the respective end ofthe link proper D. Then the link D is engaged simultaneously by both thetransverse bar E and the pin G.

From the arms E of the bar E extend outward pins E adapted to be engagedby the side arms H of a lever H, fulcrumed on the draw-head and providedwith a crank-arm H connected by a rope or chain I with an arm J ,securedon a shaft J, extending transversly and mounted to turn in suitablebearings either on the draw-head A, as shown in the drawings, or at theend of the ear. The outer ends of the shaft J extend to the sides of thecar, and are provided with arms J for manipulating the shaft J, in orderto raise the bar E and its pin Gwithout the operator stepping betweent-he cars. If desired, the shaft J is manipulated from the top of thecar by connecting its arm J with a rope or link J 3 extending throughthe top of the car. When the shaft J is turned, the arm J pulls on thelink I, so that the lever 11 is actuated and its side arms H swingupward, thus pressing against the pins E thereby raising the arms E andsupporting the bar E and the pin G. The top of the compartment is formedby a lid K, hinged at its rear end to the draw-head A, and serving toexclude dust, rain, 820.,

from the coupling. 1 The upward movement of the bar E and its pin G islimited by the pins E striking crossbars F arranged on the outside ofthe guide-ways F.

\Vhen it is desired to couple with an ordinary link only, the bar E israised, as previously described, so that the pin G slides into itsuppermost position,and the ordinary link is introduced into thecompartment B, after which the link is dropped and the cars are coupled.

Instead of the coupling-link shown in Figs. 1 and 2, a link asillustrated in Fig. i may be employed, the link proper D and thepartition D being omitted, and only the bar D with its forked ends andhooks D is used. The hook ends pass into the upper compartment C, raisethe bar E, and engage the latter, as previously described.

If it is desired to use the device for coupling a ferry-boat to a slip,then the link, as illustrated in Fig. 5, is used, having one forked endD", with hooks I), and pivoted at its other end at D on a pin L, held ina casing N, adapted to be secured to the ferry-boat and arranged topermit the link D to fall into the casing when not in use, as isillustrated in dotted lines in the said figure. The drawhead in thiscasing is arranged on the slip, and when the boat enters and the link isin the position shown in Fig. 5 then the hooks D pass into thecompartment 0, raise the bar E and engage the latter, as abovementioned, so that the ferryboat is coupled to the slip.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a coupling, the combination, with a transverse bar mounted toslide vertically in the draw-head and provided with adownwardly-extending pin, of a couplinglink provided with a link properadapted to be engaged by the said pin and with a forked bar having hooksat its ends adapted to engage the said bar, substantially as shown anddescribed.

In a coupling, the combination, with a draw-head provided with an upperand a lower compartment, of a bar extending transversely in the saidupper compartment and fitted to slide verticallyin the said draw-head, apin proj ecti n g downward from the said bar to pass into the lowercompartment, and a coupling-link adapted to be engaged by the said barand the said pin, substantially as shown and described. I
